A nurse is collecting data from a 6-month-old infant. Which of the following findings should the nurse expect?
The infant has a pincer grasp.
The infant drops objects with the expectation of someone picking them up.
The infant makes babbling sounds.
The infant crawls on their hands and knees.
The Correct Answer is C
Choice C reason: The infant makes babbling sounds. At 6 months of age, it is typical for infants to engage in babbling sounds. Babbling is a significant milestone in language development during infancy. It involves the repetition of consonant-vowel combinations (e.g., "ba-ba,”. "ma-ma") and is an essential precursor to later language skills, such as forming words and sentences. The nurse should expect the 6-month-old infant to be making these babbling sounds as part of their normal development.
Choice A reason:
The infant has a pincer grasp. A pincer grasp is the ability to pick up small objects using the thumb and index finger. This fine motor skill typically develops around 9 to 12 months of age. At 6 months old, infants have not yet acquired the pincer grasp. Therefore, the nurse should not expect the 6-month-old infant to demonstrate this skill during the assessment.
Choice D reason:
The infant crawls on their hands and knees. Crawling is a gross motor skill that usually emerges between 7 to 10 months of age. While some infants may start crawling earlier or later, it is not a skill that is typically present in a 6-month-old. Therefore, the nurse should not anticipate the 6-month-old infant to be crawling on their hands and knees during the assessment.
Choice B reason:
The infant drops objects with the expectation of someone picking them up. This behavior, known as "object permanence,”. is a cognitive milestone that develops around 8 to 12 months of age. At 6 months old, infants have not yet fully developed this concept. They might drop objects as part of their exploratory behavior, but they do not yet understand the expectation of someone picking them up. Therefore, the nurse should not expect the 6- month-old infant to exhibit this specific behavior during the assessment.

Correct Answer is B
Explanation
The fracture does not cross through the bone. Choice A reason:
The statement in Choice A is incorrect because it describes a greenstick fracture as the bone bending and causing a microscopic fracture line. This is not true for a greenstick fracture. A greenstick fracture is an incomplete fracture where the bone bends and partially breaks on one side while remaining intact on the other side. The rationale for this is that pediatric bones are more flexible than adult bones, and when a force is applied, they tend to bend rather than completely break.
Choice B reason:
Choice B is the correct answer. A greenstick fracture does not cross through the bone; it involves only one side of the bone being broken while the other side remains intact. This type of fracture is common in children because their bones are still developing and contain more collagen, making them more flexible and prone to bending rather than breaking completely.
Choice C reason:
The statement in Choice C is incorrect because it describes a different type of fracture. A compressed fracture involves the bone being crushed or shortened, leading to a raised area at the fracture site. This is not characteristic of a greenstick fracture, which involves bending and partial breakage rather than compression.
Choice D reason:
The statement in Choice D is incorrect because it describes a complete fracture that completely divides the bone into two separate pieces. A greenstick fracture, as explained earlier, is an incomplete fracture and does not completely divide the bone.
Correct Answer is B
Explanation
Choice A reason:
The WBC count of 10,000/mm is within the normal range, indicating a normal white blood cell count. There is no cause for concern, and the nurse does not need to report this result to the provider.
Choice B reason:
The Hgb level of 6.8 g/dL is significantly below the normal range, which indicates severe anemia. Menorrhagia, or heavy menstrual bleeding, could be a potential cause of this low hemoglobin level. Anemia can lead to various complications, including fatigue, weakness, and decreased oxygen delivery to tissues. This result requires immediate attention, and the nurse should promptly report it to the healthcare provider for further evaluation and management.
Choice C reason:
The Creatinine level of 0.8 mg/dL is within the normal range. Creatinine is a marker of kidney function, and a normal value suggests that the kidneys are functioning adequately. Since the result is normal, the nurse does not need to report this to the provider.
Choice D reason:
The Potassium level of 3.5 mEq/L is within the normal range, indicating a normal potassium level. There is no immediate concern with this result, and the nurse does not need to report it to the provider.
